A young motorcyclist who overestimates his abilities, boasts of his riding skills when in reality he has none. Squid bikes are usually decorated with chrome and various anodized bits. Rear tyres are too wide for their own good, swingarm extended. Really slow in the corners, and sudden bursts of acceleration when a straight appears. Squids wear no protection, deeming themselves invincible. This fact compounds intself with the fact that they engage in 'extreem riding'--performing wheelies and stoppies in public areas. Squids wreck alot. Derived from 'squirly kid'

An extremely rare animal with a short lifespan. Usually a new sport bike enthusiast with the reasoning of a lunatic, whom you might see thrashing on an R1 wearing sandals, shorts, and a tee.
When found lying motionless on the pavement, this creature transforms itself into a stream of blood, exposed flesh, and broken limbs. Hence the squid moniker.

Stupid
Quick
Underdressed
Imminently
Dead

Did you see that guy leave the showroom on the R6? Did you see what he was wearing? What a moron. That Squid.

'Squid' is a contraction of "Squirrelly Kid", and comes from So Cal racers who were also involved in the Surfer culture.

Though the term is now widely used to describe street riders of questionable cornering skill, questionable judgement in demonstrations of horsepower and braking, questionable judgement in the protective clothing worn, and very questionable judgement in his/her friends, the meaning was actually developed at the racetrack.

Back in the day before trackdays (an organized event to allow anyone with a motorcycle and the price of admission to gain familiarity with a racetrack and learn to ride faster, more safely than on the street) were common and new racers frequently had no track experience - hence their unpredictable behavior and unsteady lines led to them being labelled "squirrelly", as unpredictable surfers (or surfing conditions or surfing equipment) were also called.

From there, the term made it to the canyons of Southern California (a popular means to risk one's hide while demonstrating riding skill at speeds well over the posted limit), then out to the rest of the world that reads about So Cal in magazines and apparently strives to be just like So Cal.

"I really hate dealing with the street squids riding over their heads in the 'A' group at Buttonwillow."

"That trackday org is all about getting money from the squids who don't know better."

"Yeah, there was another squid taken off Palomar in an ambulance this morning."

v. 'to squid'. A sexual technique whereby immediately prior to the male's ejaculation the female's parent, boyfriend or other threat enters the room. The male then turns to face the intruder, ejaculating onto them, thereby creating a distraction and allowing an expedient getaway. From the method by which squid spray ink at predators to ease escape.

"I was boning this totally hot chick on her parent's kitchen table when they walked through the door. Luckily i squidded right on her dad before diving out the window"
